Study Plan
Learn the Theory
Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: Basic Properties of Magnets, Magnetic Field and Field Lines, Torque on a Magnetic Dipole.
Practise
Solve the textbook exercises and extra practice questions. There are 42 questions available for this chapter.
Revise & Test
Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.
Spaced Revision
Come back to Magnetism after a week. Use flashcards for quick recall and try past exam questions on this chapter.
What to Focus On
- Magnets attract iron, nickel, and cobalt.
- Directive property: Freely suspended magnet aligns in N-S direction.
- Attractive property: Strongest at poles.
- Magnetic field is a vector represented by B.
- Magnetic field lines show direction and strength of B.
- Field lines are closed curves — from N to S outside, S to N inside.
- A bar magnet in a uniform field experiences torque, not net force.
- Torque τ = MB sinθ.
- Magnetic moment M = m × l.
Common Mistakes to Avoid
Magnetic field lines start at the north pole and end at the south pole, just like electric field lines.
The Earth's magnetic north pole is near the geographic north pole.
Magnetic flux depends only on the strength of the magnetic field and area, not on orientation.
Memory Tips
Directive Property of Magnets: Freely suspended magnet aligns in North-South direction
Attractive Property: Maximum attraction at poles
Like poles repel, unlike poles attract
Magnetic field lines form closed loops: Outside from N to S, inside from S to N
